Kaempferitrin

The most-developed and most kaempferitrin-specific activity. Kaempferitrin acutely stimulates ¹⁴C-glucose uptake in rat soleus (skeletal) muscle in an insulin-mimetic, insulin-signaling-dependent manner ^{1Reference 1Jorge AP et al. · 2004AnimalInsulinomimetic effects of kaempferitrin on glycaemia and on ¹⁴C-glucose uptake in rat soleus muscleView study →}, activates insulin signaling and adiponectin secretion in adipocytes ^{3Reference 3Tzeng YM et al. · 2009Kaempferitrin activates the insulin signalling pathway and stimulates secretion of adiponectin in 3T3-L1 adipocytesView study →}, drives glucose uptake in skeletal muscle ^{5Reference 5Cazarolli LH et al. · 2013Insulin signalling: a potential pathway for the stimulatory effect of kaempferitrin on glucose uptake in skeletal muscleView study →}, and in mice modulated hepatic AMPK phosphorylation and lowered PEPCK (gluconeogenesis) after a high-fat/high-sucrose diet ^{6Reference 6Garofolo IC et al. · 2026AnimalKaempferitrin modulates AMPK phosphorylation and PEPCK expression in the liver after a short-term high-fat, high-sucrose diet in miceView study →}.

The classic in-vivo anchor is a hypoglycemic + antioxidant effect in diabetic rats for the isolated dirhamnoside from Bauhinia forficata ^{2Reference 2de Sousa E et al. · 2004Hypoglycemic effect and antioxidant potential of kaempferol-3,7-O-(α)-dirhamnoside from Bauhinia forficata leavesView study →}.

Gap: all preclinical, and tissue-divergent — one adipocyte study reports kaempferitrin inhibits GLUT4 translocation and glucose uptake ^{4Reference 4Vishnu Prasad CN et al. · 2009Kaempferitrin inhibits GLUT4 translocation and glucose uptake in 3T3-L1 adipocytesView study →}, conflicting with the muscle picture, with no standardized dose-response and no human trial ^{1,4Reference 1Jorge AP et al. · 2004AnimalInsulinomimetic effects of kaempferitrin on glycaemia and on ¹⁴C-glucose uptake in rat soleus muscleView study →Reference 4Vishnu Prasad CN et al. · 2009Kaempferitrin inhibits GLUT4 translocation and glucose uptake in 3T3-L1 adipocytesView study →}.

Kaempferitrin shows consistent NF-κB restraint across unrelated models: it attenuated LPS-induced septic acute lung injury ^{7Reference 7Zhu X et al. · 2023AnimalKaempferitrin alleviates LPS-induced septic acute lung injury in mice through downregulating the NF-κB pathwayView study →}, inhibited proliferation and inflammation in rheumatoid-arthritis synoviocytes ^{8Reference 8Wang J · 2019Kaempferitrin inhibits proliferation, induces apoptosis and ameliorates inflammation in rheumatoid-arthritis fibroblast-like synoviocytesView study →}, and reduced renal inflammation and fibrosis by inhibiting NOX4-mediated tubular ferroptosis ^{9Reference 9Li J et al. · 2024Kaempferitrin attenuates unilateral-ureteral-obstruction-induced renal inflammation and fibrosis by inhibiting NOX4-mediated tubular ferroptosisView study →}.

Gap: three single-model rodent/cell studies, with no replication or human data, largely shared with the kaempferol/flavonol class ^{7,8Reference 7Zhu X et al. · 2023AnimalKaempferitrin alleviates LPS-induced septic acute lung injury in mice through downregulating the NF-κB pathwayView study →Reference 8Wang J · 2019Kaempferitrin inhibits proliferation, induces apoptosis and ameliorates inflammation in rheumatoid-arthritis fibroblast-like synoviocytesView study →}.

Kaempferitrin’s antioxidant activity overlaps its antidiabetic story: radical scavenging linked to hypoglycemia in diabetic rats ^{2Reference 2de Sousa E et al. · 2004Hypoglycemic effect and antioxidant potential of kaempferol-3,7-O-(α)-dirhamnoside from Bauhinia forficata leavesView study →} and protection of mesangial cells from advanced-glycation-end-product-induced apoptosis and oxidative stress ^{14Reference 14Jiang W et al. · 2018Protective effects of kaempferitrin on advanced-glycation-end-product-induced mesangial-cell apoptosis and oxidative stressView study →}.

Gap: class-level flavonol antioxidant behavior in narrow models, not distinctively kaempferitrin ^{2,14Reference 2de Sousa E et al. · 2004Hypoglycemic effect and antioxidant potential of kaempferol-3,7-O-(α)-dirhamnoside from Bauhinia forficata leavesView study →Reference 14Jiang W et al. · 2018Protective effects of kaempferitrin on advanced-glycation-end-product-induced mesangial-cell apoptosis and oxidative stressView study →}.

Kaempferitrin induces intrinsic apoptosis in HeLa cells ^{10Reference 10Alonso-Castro AJ et al. · 2013Kaempferitrin induces apoptosis via the intrinsic pathway in HeLa cellsView study →}, and as the major compound of an epazote ethanol extract it produced antitumor and hepatoprotective effects in a human-liver-cancer mouse xenograft without hepatotoxicity ^{11Reference 11Su M et al. · 2023AnimalKaempferitrin, a major compound from the ethanol extract of Chenopodium ambrosioides (epazote), exerts antitumour and hepatoprotective effects in mice with human liver-cancer xenograftsView study →}.

Gap: heterogeneous and exploratory — single studies at the isolate or extract level, with no translational follow-up ^{10,11Reference 10Alonso-Castro AJ et al. · 2013Kaempferitrin induces apoptosis via the intrinsic pathway in HeLa cellsView study →Reference 11Su M et al. · 2023AnimalKaempferitrin, a major compound from the ethanol extract of Chenopodium ambrosioides (epazote), exerts antitumour and hepatoprotective effects in mice with human liver-cancer xenograftsView study →}.
